When it started as a way for callow, pizza faced youths to rate young women on whether or not the youths would like to fuck them, keeping them on the service wasn't hard, just supply them with stock photos of women and they'd be happy looking at ads for Axe..
Their algorithm is designed to feed people what they want. Click on a post about skiing, you're deluged with adverts on resorts, equipment, tips and tricks, ad nauseum. It was always about delivering you to advertisers while keeping you interested enough to stay on the site to the exclusion of all others.
Once politicians discovered it, it was mostly over. Once Putin discovered it, it was weaponized.
Now it's a toxic stew of negativity and most subscribers still aren't aware of what's been happening to them. They really think they're in control, while every day they get more depressed and angrier.
That's because the algorithm that decides what to give you instead of what you want or need is in control. It was designed to deliver you to corporate advertisers. It is now delivering people to the vilest propaganda out there because it was wide open and vulnerable to slick psyops campaigns.
It's way overdue for regulation and redesign. It's killing us.
